Intelli-Hood Hong Kong Hotel Retrofit Case Study


Author: Randy Miles – Dec 29, 2016

CONTEXT

With 602 beautifully designed rooms and 8 luxurious restaurants and lounges, The JW Marriott in Hong Kong, China sought to save energy and reduce their carbon footprint while offering a 24/7 dining service. In 2014, they decided to install Melink’s patented Intelli­-Hood® demand control kitchen ventilation as a means to  reach this goal. Here is more information regarding the hotel kitchens:

  • Total motor power: 15 HP
  • Daily operating hours: 24
  • Days per week: 7
  • Weeks per year: 52
  • Cost per kilowatt hour: $0.14


RESULTS

Intelli-Hood saved $8,249 in utility costs and reported an average fan speed of 76%. This resulted in a 2 year payback and and reduced carbon emissions.  The JW Marriott team is very pleased.
